冷冻系统杂质如何沉浸

水对系统的影响

I.ce扩展阀插件,导致流水供应差

二. 润滑油部分稀释,减润滑性能

三.Hydrocrication和He

四.电阻递减

处理系统水流法

冷却系统水摄取不严重, 数次修改干滤波会很好. 如果系统有大量水, 我们需要用氮冲刷段内污染, 替换滤波, 冷冻油和冷冻剂,直到颜色变绿

2. 非冷凝气体对系统的影响

所谓的非冷凝气指冷却系统工作时,在冷凝器特定温度和压力下,气体无法凝结为液态,但总不能凝结为气态这些气体主要包括氮气、氧气、氢气、二氧化碳、油气气、惰性气体和这些气体混合体

非冷凝气体会增加压缩压力,提高排气温度,减少冷却能力并增加电耗特别是当氨用作冷媒时,非冷凝气往往会爆炸

系统处理法非压缩气

关闭冷凝器排气阀并启动压缩机,将冷凝器从低压系统泵到冷凝器或高压水库

停止压缩机并关闭吸管打开冷凝器最高点喷口阀

空气温度随手可见.当没有冷感或热时,大多数排出物为非冷凝气,否则为冷凝气

检验饱和温度与高压系统压力和冷凝器排气温度之差

如果温度差大,则表示更多非冷凝性气体,应在混合完全冷却后间歇释放

石油胶片对系统的影响

Although there is an oil separator in the refrigeration system, the oil that has not been separated will enter the system and flow with the refrigerant in the pipe to form an oil circulation.If oil film is attached to the surface of heat exchanger, the condensation temperature will rise and the evaporation temperature will drop, resulting in the increase of energy consumption.When the oil film of 0.1mm was attached to the surface of the condenser, the refrigerating capacity of the refrigerating compressor decreased by 16% and the electricity consumption increased by 12.4%.When the oil film is 0.1 mm inside the evaporator ,evaporation temperature will drop by 2.5 ℃, power consumption will rise by 11%.

处理法系统有油膜

发现反流油问题不适当设计蒸发器和煤气回流管道并不少见高效石油分离器的使用可大大减少流入系统管道的油量。
